Description
This “as new” used Heidolph MR Hei-Tec with PT 1000 sensor has never been used in practice by the previous owner, strange but true. Therefore, it is still “as new” packed in the original box (see pictures). We tested it and it is in a perfect state.
This variant includes the Pt 1000 temperature probe – for precise temperature control, overshoot protection and reproducible results. It features a digital display and allows for easy setting and monitoring of values in the illuminated readout. For your protection an independent safety circuit will switch off heating if hotplate temperature exceeds 25 °C over set temperature.
Digital speed setting from 100 to 1,400 rpm at an accuracy of ± 2 % and temperature setting up to 300 °C. A separate on/off switch for heating prevents an unintentional heat-up. If heating is switched on the on/off button is illuminated for visual control. In addition, a residual heat indicator prevents from burning hazards when heat function is switched off. An illuminated button indicates clearly if the stirring mode is activated. To protect your sample from overheating a safety circuit switches off heating if the temperature sensor is not immersed in your media vessel.
